Espruino Pico is a tiny microcontroller board that runs JavaScript(it doesn't need to be plugged into a computer)、making it easier than ever to control electronics in the real world. You can program it with nothing but a serial terminal program、but there's also an IDE that runs in the Chrome Web browser. It's got a syntax highlighted editor as well as a graphical programming language.。Once you have uploaded code、you can inspect and change variables(including functions)while your program is running. If you make something with an Espruino Pico and need to change it a year later、your original code is still there waiting for you!。This is unpinned version、if you want pre-soldered pins、please visit Espruino Pico(pinned).。Features：33mm×15mm(1.3×0.6 inch)。22 GPIO pins：9 Analogs inputs、21 PWM、2 Serial、3 SPI、3 I2C。All GPIO is 5 volt tolerant(Arduino compatible)。2 rows of 9 0.1" pins、with a third 0.05" row of 8 pins on the end。On-board USB Type A connector。Two on-board LEDs and one button.。STM32F401CDU6 CPU - ARM Cortex M4、384kb flash、96kb RAM。On-board 3.3v 250mA voltage regulator、accepts voltages from 3.5v to 16v。Current draw in sleep：< 0.05mA - over 2.5 years on a 2500mAh battery。On-board FET can be used to drive high-current outputs。Part List：Espruino Pico(unpinned)x 1

It's interesting to hack one of your appliances or lighting projects into a whistle controlled intelligent one. The whistled allows you to do so by simply whistling two musical notes. To set it up、you just need to connect your 5.5/2.1mm DC connector on one end and your load on the other.。Specifications。ESD protected PCB、covered in transparent heat shrinkable tubing。Voltage must be between 4.5 and 18V at the input(barrel connector)。Reversed polarity protection。Max current of 5A。16 bits PWM output。SWD pads for programming。Listening range of 15m / 50feet。Cortex M4 microcontroller performing 80 FFTs / sec。Maximum voltage on the screw terminals is 25 Volts(don't forget the flyback diode!)

5V/3.3V breadboard power supply designed by SeeedStudio. It can directly takes power from DC wall wart and outputs both 5V and 3.3V regulated voltage. Compare to other breadboard power supply designs、this one provided micro-USB port、you can use both 5V and 3.3V regulated voltage. The 5V/3.3V breadboard power supply includes micro-USB port and power jack port. This power supply fits the breadboard which is 5.3cm wide like Bread board Clear - 8.2×5.3cm、and it can fit the 5.5cm wide breadboard too Basic Bread board - 16.55.5 cm、but just a little tight.。Features：Dual lane outpu。Dual power port input。5V/3.3V regulated voltage。Maximun output current is 400mA。Part list：5V/3.3V Breadboard Power Supply Board 1。Specification：Input voltage：7V 15V。Output Voltage：3.3V Channel：3.267V - 3.333V。5V Channel：4.9V 5.1V。Output current 400mA

Espruino is a small computer that anyone can use to control things around them. Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you've never written code before、you can still use the graphical code editor to write programs without typing a single word!。Features：Works on Windows、Linux、MacOS and Android(via Bluetooth or USB OTG)。Less than half the size of a business card just 54mm×41mm。Using the popular JavaScript language、Espruino supports Strings、Maps、Objects、and Dynamic Arrays right out of the box!。72Mhz ARM microcontroller with 256KB of Flash memory and 48KB of RAM。Micro USB connector、Micro SD card connector、and a JST Battery connector with a wide input voltage range of 3.6v to 15v。Red、Green and Blue LEDs、with 2 pushbuttons(one of which is reset by default)。Solder an HC-05 Bluetooth module(not included)directly onto the board and program and debug Espruino wirelessly!。44 GPIO pins on a 0.1''pin spacing、with 26 PWM pins、16 ADC pins、5 USARTs、3 SPI、2 I2C and 2 DACs。Power Consumption：35mA run、12mA sleep、<0.05mA in deep sleep。Prototype area which can be used for servo headers、wireless modules and SOIC surface mount parts such as motor drivers。Built in drivers for the TI CC3000 WiFi and WIZnet W5500 Ethernet modules(not included)、as well as a graphics library with vector font Open Source software and hardware。Espruino Website with full documentation、many tutorials、and an active forum。CE and RoHS Compliant。On-chip RTC with external 32kHz Oscillato
